However, there is a lack of relevant clinical reports regarding rectal metastasis. Herein, we report the rare case of a patient with gastric cancer who developed rectal metastasis. A 57-year-old male patient was diagnosed with gastric cancer and underwent a radical gastrectomy in January 2016, followed by eight cycles of adjuvant chemotherapy. The patient subsequently developed a rectal mass in March 2021. He was diagnosed with rectal adenocarcinoma and underwent surgical resection of the rectal tumor. A mass was then found in the abdominal wall in September 2021 and was resected. Specimens obtained from the three surgeries were reviewed, and the rectal tumor and the mass in the abdominal wall were both found to be metastatic tumors from the gastric cancer. Metastasis of gastric cancer to the rectum is rare, but it is important to differentiate between rectal metastasis and primary rectal cancer to help avoid unnecessary treatment.  \nKeywords  \nRectal metastasis, gastric cancer, rectal cancer, metastasis, differential diagnosis, case report  \nDate received: 5 November 2022; accepted: 15 August 2023  \nIntroduction  \nGastric cancer is one of the most common tumors worldwide, with an especially high incidence rate in developing countries.1 Patients with advanced gastric cancer often have distant metastases, especially involving the liver, peritoneum, lung, and bone.2 Rectal metastasis is relatively uncommon and there is currently a lack of  \n1 Guangzhou University of Chinese Medicine, Guangzhou, China  \n2Zhongshan Hospital Affiliated to Sun Yat-sen University, Zhongshan, China  \n3Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of tradition, Zhongshan, China  \n*These authors contributed equally to the work, Corresponding author:  \nJincheng Meng, No.3 Kangxin Road, Zhongshan 528400, China.  \nEmail: [Jinchengmenggzucm@163.com](Jinchengmenggzucm@163.com)  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative  \nCommons Attribution-NonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use, reproduction and distribution of the work without further permission provided the original work is attributed as specified on the SAGE and Open Access pages ([https://us.sagepub.com/en-us/nam/open-access-at-sage](https://us.sagepub.com/en-us/nam/open-access-at-sage)).  \nrelevant clinical reports.

No tumor recurrence was recorded during follow-up. In March 2021, however, the patient was hospitalized with a complaint of poor defecation. Physical examination and colonoscopy revealed a rectal mass located 4cm from the anus (Figure 1) . Magnetic resonance imaging examination also showed a rectal mass suggesting rectal cancer. A biopsy of the mass showed superficial intestinal mucosal tissue, interstitial edema with inflammatory cell infiltration, and mild glandular hyperplasia, but no tumor cells.
